[Q] Custom Ringtone/Notification sounds email contact

I have made the switch from a nice blackberry torch 9800- which I had no issue with at all. It was getting super tired and needed to be put to rest, it is grateful.

The new HTC does everything better than the torch(shocking, I KNOW!). However, there is only one thing that I could do with that BB that I cannot figure out how to do with the HTC and it is a HUGE issue for me. I need a customized alert/notification/ringtone for specific email contacts (SMS would also be nice, but not a major issue). In other words when I get an email (gmail only) from someone specific, I need the notification tone/ringer to tell me I have email from them, specifically. I really only have 3 or 4 that need to be customized.

I have several international contacts who I do not speak to on the phone (i.e. they do not call me) so, I do not have telephone numbers for them. I have Skype addresses and email addresses for them. With the BB, I added them to contacts (w or w/o a phone number) and if I received an email to my gmail account I was alerted with a specific chosen ringtone. Email that was sent from others had a generic notification tone.

Is there an app? a tweak? something I am missing? If the BB can handle this, surely Android can do the same? I have added them to my phone contacts and entered the email address in the information- chosen the specific tone for that contact. I have received emails from them and I still just get the standard default email notification sound.
thanks for your help!
